    My Latest (and Greatest!) Project - A Lisp (like) interpreter .

    This is actually my first project that does something 'useful' !

    Here is the code:
    https://github.com/manasij7479/minlisp

    Read the README first and if it seems interesting enough, just download the zip from the link there(top left ) and 'make' it.

    I've a challenge for anyone who builds it...: Try to crash the program !!
    (I myself have managed to do it by defining a infinitely recursive function..., but can't find anything else )

    I'd very much like a superficial (or deep...if any of you've got some time) review of my code here.
    (I know there are some gotchas to be fixed ...like avoiding const in some places and still using copy instead of move ...which I'll fix as soon an I can)

    P.S: To windows users, can you test if the code compiles cleanly over there ?

    I think it is a problem with the line endings.. (Any idea how to automatically fix that?...or would doing that bring such problems for my computer?)
    Because I can't relate any of the errors to the code convincingly..
    (It compiles without an extra word in my machine)

    Might be because I downloaded the files manually. I don't have Git on my work comp.

    Even when downloading (the zip) manually it compiles for me.

    It worked fine with the zip. They need a bigger button for the zip download because I didn't see that button at all when I went to the page before.

    Typing in the EOF character makes it printout [minlisp] nonstop though.

    Happens for me too..
    I tried iscntrl() but it did not work..(i.e.. no effect).
